Did you know?
The Indiana bat hibernates in mines and caves, but males and females roost in crevices and under the bark of trees during the warmer months of the year. Female Indiana bats form maternity colonies, giving birth and raising their young in these tree roosts.

This species was federally-listed as endangered prior to the start of white-nose syndrome and subsequently suffered population declines of 71% from 2007-2015. Many of the general areas where maternity and bachelor colonies are known to occur are in areas that are subject to increasing development.

The maximum total count increased from approximately 13,000 to 41,000 Indiana bats from 2001-2006. This increase in numbers was largely the result of discovery of new hibernacula and improved methods of counting overwintering bats but may also have reflected an increase in the overall size of the population. Winter hibernacula surveys from 2007-2015 documented population declines of 71%.
